Use Vault to vault the NetBackup catalogs. A current catalog backup is a critical component of an effective disaster recovery plan. Although you can rebuild the catalog by importing all of your backup media manually, it is a time-consuming process.
Vault requirements and guidelines are as follows:
Perform the catalog backup step in Vault. Vault creates a new catalog backup with up-to-date information, it does not duplicate an existing NetBackup catalog backup. A NetBackup catalog backup is not a substitute for a Vault catalog backup. It does not include the latest information about duplicated media and media location.
Retain the three most recent catalog backups. In most circumstances, you do not need to retain vaulted catalog backups for the same length of time that you retain other vaulted backup media. Although you only need one catalog backup in your offsite vault, for extra protection, maintaining the three most recent catalog backups in your offsite vault is a good practice. The Recovery Report for Vault lists only the three most recent catalog backups in the offsite vault regardless of how many actually reside in the vault.
To retain only the three most recent catalog backups, specify an appropriate retention level so that older catalog backups expire and are recalled from offsite storage and only the three most recent catalog backups remain in offsite storage.
